Residual risk represents the difficulty in estimating the project scope, time, and costs during the later stages of the project. As such, the measure is an outcome of development steps and indicates estimation difficulty, not why estimation is difficult, or the methods used in estimation.


Measurement items:

R1: What the cost of the project would be (removed)
R2: What the project completion time would be
R3: What the benefits of the project would be
R4: If software would be compatible with environment
R5: If software would meet user need
